1 INTRODUCTION

1.1 WHY POWERSOFT?

To correctly and efficiently manage any electrical distribution system, mainly

considering the cost reduction point of view, it is important to monitor the energy

consumptions, to control the demanded power peaks and to exploit accurate data

processing and analysis tools.

PowerSoft is a sophisticated data acquisition and processing system

developed to satisfy these requirements and to supply a very flexible but easy-to-use

Energy management tool.

PowerSoft


1.2 FEATURES

PowerSoft is modular software consisting of a main core (which includes the

data acquisition and database functions) and of a series of optional modules that

allows adding different features to satisfy different requirements or to solve specific

applications.

The software can automatically adapt itself according to the electrical system

configuration. In this way the user can easily configure the instruments and the

software (parameters and synoptic pages) without the need of particular

programming or computer knowledge.

1.3 GENERAL SPECIFICATIONS

PowerSoft is an analysis platform suitable for Win XP and Vista, which has been specifically developed to interface, by means of the Modbus protocol (RTU and TCP/IP), the Carlo Gavazzi products for Energy Management.

The system is composed by a main module (called “core”) and by a series of

modules, some of which are included in the base package (ordering code

“POWERSOFT”). The core module communicates with the instruments, shows

the real-time variables, and stores the acquired data in the system, while the other

modules tasks are to process the stored data, to analyse the acquired information, to

create reports.

In detail, the core:

provides the interactive and animated synoptic pages that

allow:

o to display the plant configuration

o to display the real-time data

o to monitor the digital input status acquired by the

instruments on the field

PowerSoft


commands the instruments digital outputs, manually or

following an alarm situation

displays an alarm window that informs the user in case

of set point exceeding or communication errors

has 3 access level, protected through a password.

Every further operation is carried out through the optional modules. No

additional module is necessary for the core operations. The available optional

modules are the following.

Trends (analytical and graphical, included in the base package

“PowerSoft”): A selectable set of variables (different from

instrument to instrument) can be stored in the PowerSoft database

with a selectable time interval. All the data can be analysed later on in

both graphical and analytical format and exported in various formats

(wmf, csv, xls). Up to 4 variables (from the same or from different

instruments) can be contemporarily displayed. With simple and

intuitive procedures it is also possible to zoom the graph or analyse it

in detail with a cursor, freely choosing the time period to be displayed.

If the tariffs and the different contractual powers are set (if the “PWS-

Tariff” module is available), this information can be graphically

related to the stored variables.

Active alarm/Alarm and Events (included in the base package

“PowerSoft”): an active alarms window (that automatically pops up

in any case of alarm) advises the user if a set point has been exceeded

or if a communication error is present; it allows the qualified users to

acknowledge the selected alarm. An alarms and Events log allows to

access the archive of the events (login, logout, start-up, alarm

acknowledgment, etc.) and of the alarms (set point alarm,

communication errors, missing data storage, etc.) and to carry out

filter-based searches.

PowerSoft


Set point configuration (optional module “PWS-Alarm”): the set

point alarms can be associated to both an up and a down threshold

on all the variables measured by all the instruments of the network.

The alarm can be software, being displayed in the Active alarms

windows and stored in the Alarms and events log, or hardware-based,

being stored as above and switching the digital output of the

instrument that are pointing out the anomaly. If the PWS-Tariff

module is available, the set point on the active power can be in

function of the current tariff.

Tariffs configuration (optional module “PWS-Tariff”): the

different tariffs during the day and the distribution of the typical-days

among the year can be set according to the supplier tariff regulations

in a very easy and extremely flexible way. It can manage: up to 12

tariffs; up to 24 tariff change per day; up to 365 different typical-days

per year. For each tariff the relevant contractual power can be edited

to be displayed on the graphics or to be used as a set point to avoid

overpower demands (if the “PWS-Alarm” module is available).

Analysis support (optional module “PWS-Analysis”): it carries

out statistical analysis on the power trends and energy consumption

by extrapolating the average demand of each day of the week, the

week-based consumption trends, and the estimation of the ideal

installed power for each tariff, calculated with a selectable confidence

level. The data can be filtered removing from the computation, if

needed, the week-ends, the holidays and the days with anomalous

consumption due to external events.

Costs estimation (optional module “PWS-Bill”): according to the

utility contract parameters, the module allows to estimate the costs,

relevant to a selected period, due to the energy, water and gas

consumption. This is useful to perform the cost allocation among the

monitored lines, to display the daily trend of the consumption or to

identify the reasons of any penalty.

PowerSoft


E-mail (optional module “PWS-Mail”): it manage the automatic

e-mailing, able to notify the electrical system status to one or more e-

mail addresses. The e-mailing can be carried out on regular basis

and/or as a consequence of a defined alarm or event.

Web-server (optional module “PWS-Web”): the web-server

module allows to remotely accessing PowerSoft, using a standard

browser without additional licenses, in order to access all the real-time

information and historical data.

Harmonic Analysis (optional module “PWS-Waves”): the waves

module allows to display the wave-form of the voltage and current

signal. It is possible to show this information through a trigger

command only, it is possible to manage three types of trigger: manual,

automatic and continuous. After a trigger command it is possible to

see 10 cycles before the trigger event. It is possible to use this module

with the WM5 and PQT-H only.

XLS Report: (optional module “PWS-Report”): the report module

allows to export all acquired data in an excel file. It is possible to

create personalized reports according both to different installations

and customers’requests.

PowerSoft


2 INSTALLING POWERSOFT

2.1 SYSTEM REQUIREMENTS

PowerSoft needs of the following minimum requirements:

Processor: Pentium II 400

RAM: 500Mb

Hard disk: 10 Gb free

Monitor: 1024x768

Windows: XP / Vista

2.2 INSTALLATION

The installation program guides the user installing PowerSoft, allowing to

choose the default language and the installation folder, and to create an icon on the

desktop.

PowerSoft


The navigation through the installation program is carried out by means of the

“Next”, “Back”, or “Cancel” keys respectively to proceed, recede, or exit the

program and therefore not installing PowerSoft... After a successful installation, a

new entry on the “Start”/“Program” menu is available; it includes the link to

PowerSoft, the Configurator and to the relevant uninstalling program.

After the installation, PowerSoft is available with a minimum configuration

(no synoptic page, no connected instrument, etc.), therefore the configuration

program “Configurator.exe”.

If Powersoft is entered before the configuration process, a login as

Administrator is mandatory to exit the program itself (see paragraph 2.4). Only the

Administrator can exit PowerSoft.

On the system, two predefined user are set by default (see paragraph 2.4).

2.3 THE FIRST POWERSOFT START-UP

The first time Powersoft is launched, the Shareware version is immediately

active: without the necessity to insert any key code. After a test period of 30 days, a

definitive access code is required to be able to use PowerSoft again. The code

depends on the optional modules bought by the user.

This window asks for the code after the first start-up

To get the proper access code, the software supplier or distributor is to be

contacted, communicating him the access key provided by the software itself (in the

above example, see the picture, it is “HPKIFDCN”). Editing the returned access

PowerSoft


code, paying attention to the capital letters, the software and the desired modules

are available.

Without the access code, PowerSoft cannot be used. The access code will

not expire and therefore it is not to be edited again.

IMPORTANT NOTE: the code is depending on the PC and on the hard-

disk. If the software is to be moved in another PC or in a new hard-disk, a new

access code is to be asked to the supplier.

PowerSoft


2.4 USERS AND PASSWORDS

The installing program sets two default users on the system:

User 1:

Name: admin

Password: admin

Level: Administrator

User 2:

Name: user

Password: user

Level: User

These default users can access all the PowerSoft functions (according to the

relevant level, see below) but, for safety reasons, it is suggested to create at least a

new “Administrator” user (or more of them and the required simple “Users”= and

then delete both the default users.

The “User” can access all the data, acknowledge the alarms, and ask for any

report, also via web-server.

The “Administrator” can access all the “User’s functions and, in addition,

can configure Powersoft and all the relevant modules

A user without the password can only access the real-time values and display

the active alarms list.

pages generated in the configuration process. Clicking on a synoptic

page, it is automatically displayed.

The Single Meter entry includes, in its submenus, the list of all the

instruments connected to the system. Clicking on an instrument, the

real-time window of that instrument is displayed. The instrument is

grouped according to the relevant communication line. For the

details on the real-time window, see paragraph 1.11.

The All the meters entry allows to show all the measurements (in three

groups) of all the meters at the same time; in this way a global vision

of the system and a comparison among the same variables from

different instruments are possible.

The Active alarms entry opens the window showing all the active

alarms.

PowerSoft


3.1.5.1 “ALL THE METERS” MENU

To have a global vision of the system and to perform a comparison among

the same variables from different instruments, this function shows a table where all

the measurements of all the meters are available.

The available variables are grouped in three categories:

Powers and power factors

Voltages and Currents

Other variables

In each group, the first column describes the variables and the relevant

engineering unit. Each other column is dedicated to a specific instrument and

indicates the value of the variable described in the first column.

The table is split into more pages: each one of them includes five

instruments; using the arrows in the top left box (or the relevant drop-down menu),

it is possible to scroll the different pages. In the same box, there is the indication of

the current page.

To analyse a different group of variables, double click in the area between

the boxes or click once on the double arrow near the group name. The variable of

PowerSoft


more than one group can be shown at the same time, just dragging the relevant

group boxes until the desired size is obtained.

The window shows a red indication in case of setpoint alarm; in the top right

of the window, a red LED indicates the alarm situation. Another red LED is in the

variable group where the alarm situation is present, and the variable value is

highlighted.

If the alarm condition occurs in an instrument not included in the current

page, it is possible to locate the right page looking at the page drop-down menu,

where the relevant page is highlighted in red too.

PowerSoft


3.1.5.2 THE “ACTIVE ALARMS” SECTION

Clicking in this section opens the Active alarm window.

Each alarm is grouped according to its Type and Subtype; the Agent who/which

caused the alarm and the event Description are indicated too. The first three columns

include the starting, ending and acknowledgment date and time of the event.

The event has a different colour according to its status: red if the alarm is

active but not acknowledged, yellow if the alarm is active and acknowledged, and

white if the alarm is not active but acknowledged. The alarms which are neither

active nor acknowledged are automatically deleted from this window and they are

stored in the event log.

To promptly inform the user of any new alarm or of the end of an alarm

situation, the Active alarm window automatically pops up when such a situation

occurs.

The following operations are possible:

Acknowledgement: using the two top right buttons it is

possible to acknowledge the selected alarm or all the alarms

at the same time. Only a logged-in user can acknowledge an

alarm.

been preformed from this meter and that the displayed values have been updated.

PowerSoft


The buttons functions on the bottom are respectively: to enter the analytical

trends window, to enter the graphical trends window, to exit the real-time page.

The centre of the page shows the real-time data in different formats. Up to

five sections (according to the instrument model and to its programming) are

available: Indicators, Variables, Other variables, Inputs/Outputs, Fresnell.

The following paragraphs explain each single section.

3.4.1 ANALOGUE INDICATORS The Indicators section is the default one when the real-time page is opened. It

shows the active and reactive system powers, the system power factor, the phase

currents, and the active and reactive energy meters (imported and exported). It is

not possible to change the displayed variables.

PowerSoft


In the above picture, the red arrows show the setpoint values assigned to the

variables (system active power and current phase 1 in the example). Two setpoints

are available for each variable: an upper setpoint (red band, “up” type alarm) and

lower setpoint (yellow band, “down” type alarm). The minimum and maximum

values reached by the variable from the previous recording (variable data log on the

hard disk) are shown by means of two amber indicators, close to the scale.

3.4.2 VARIABLES

This section shows the real-time values of all the variables of the selected

instrument. Clicking on one of the variables, the details of the selected variable are

displayed on the bottom of the table; the details are: the last real-time value, the

PowerSoft


minimum, maximum and average values calculated from the last recording (variable

data log on the hard disk), and the time of the last recording.

If one of the variables exceeds the relevant setpoint, the background of the

same variable is red.

The background of the meters (energy, gas, or water) is always sky-blue.

3.4.3 OTHER VARIABLES This section shows the real-time values of the selected instrument not

relevant to electrical parameters, nor to gas and water meters.

The last real-time value, the minimum, maximum and average values calculated from the last recording are available as per the standard electrical variables. To add any additional variable, please contact the supplier for the relevant instructions.

PowerSoft


3.4.4 INPUTS/OUTPUTS This section shows the status of the digital inputs and the digital output of the

selected instrument. This section is available if the instrument is equipped with the

proper hardware and if the inputs/output are properly set in the configuration

process.

The status is indicated by means of both an ON/OFF text and a status LED

(respectively red/grey). If the inputs/output are not configured, they are shown in

this section as not available.

The digital output status can be manually modified by means of the “Enable”

and “Disable” buttons; the command is sent to the instrument after the positive

answer to a confirmation request. The digital output status can be changed only by

a user logged-in as “Administrator”. Once the command has been sent, the new

status can be displayed only when the system polls the relevant instrument again.

NOTE: PowerSoft can manage only one digital output per instrument (the

first one, or the first of slot D, in case of a modular instrument). This output is to

be set as “REM” directly on the instrument.

PowerSoft


3.4.5 FRESNELL

This section shows the Fresnell diagram of the branch monitored by the

selected instrument. On the right, the details of each phase (voltage, current, phase

angle between them) are shown.

5.2.1 CREATING A CUSTOMISED TABLE

The first step to create a customised analytical trend is to select the (up to

4) variables to be shown in the table. For this purpose, each column has on

the top right of the first row, a proper button clicking on which the variable

dialogue box appears. In the dialogue box it is possible to select: the

variable and the relevant instrument. The values to be shown can be the

real-time ones, or the minimum, the maximum or the average from the last

recording on the hard disk. The availability of these different values is set in

the configuration of the instrument properties (Configurator), when the

values to be stored are decided.

The Show button changes the variable on the selected column, while Cancel

leaves the previously displayed values.

Once the variables are configured, the period of time to be analysed is to be

set. On the left the starting and ending time and dates can be set. Clicking

on the Modify period button changes the period displayed in the report.

5.2.2 PREDEFINED TRENDS

To simplify the use of this module, a series of predefined reports are

available using the boxes in the top left square. For each instrument,

selectable in the upper box, a number of predefined combinations of

PowerSoft


variables can be selected. The chosen variables of the instrument are

displayed with reference to the time period set in the relevant square.

NOTE: other predefined trends can be added to the system. Please contact

the supplier for the relevant instruction.

5.2.3 CONSUMPTION/GENERATION DAILY REPORT

By means of this function of the Analytical trend module, it is possible to export the information regarding the daily energy consumption and/or generation, just specifying the reference period and clicking on the “Daily export” button, in the bottom left area. The result is an Excel file similar to the following one.

PowerSoft


5.3 GRAPHICAL TRENDS

This module allows displaying the logged data as a graph. In the same

graph up to 4 variables (of the same or of different instruments) can be

shown at the same time.

5.3.1 ANALYSING A GRAPH

The information relevant to the programmed trends is displayed on the

legend on the left side: each part of the legend is relevant to the trend. The

following picture is an example of one of the legend blocks.

In the legend the name of the variable, the relevant instrument, and the

value (with the engineering unit) which is pointed by the mouse cursor in

PowerSoft


the graph are described. The coloured rectangle is the reference to the

colour of the trace.

In the same row of the legend title, there are two buttons. The left one

disables the displaying of the relevant trend (it is green if the trace is

enabled, red if disabled). Clicking on the right one, the variable selection

dialogue box appears.

Below the legend, a square indicates the date and time pointed by the

mouse cursor.

In the top of the window there is the graph tool bar.

The tool bar includes:

The date of the displayed data.

The displayed time interval. If 1 is selected, the time interval is 1

day. 7 means one week and 31 one month. The displayed

week or month are the ones including the date on the tool

bar.

If the PWS Tariff module is available, selecting T it is possible to

display in the graph background the different tariffs,

represented by different colours.

It is possible to enable the automatic updating of the graph, which

is updated every time a new value is acquired from the

system.

PowerSoft


5.3.2 CREATING A CUSTOMISED TREND

The first step to create a report is to select the (up to 4) variables to be

shown in the table. For this purpose, the cross-shaped buttons on the

legend are to be clicked after which the variable dialogue box appears. In

the dialogue box it is possible to select: the variable and the relevant

instrument. The values to be shown can be the real-time ones, or the

minimum, the maximum or the average from the last recording on the hard

disk. The availability of these different values is set in the configuration of

the instrument properties (Configurator), when the values to be stored are

decided. The trend can be displayed as a line or as a histogram, according to

the selection in the graph type box.

The Show button changes the variable on the graph, while Cancel leaves the

previously displayed trend.Once the variables are configured, the period of

time to be analysed is to be set in the graph tool bar. By means of the

button, it is possible to select the desired date. The extension of the

displayed time period is to be selected among 1 day, 1 week, or 1 month

(respectively using the 1, 7, or 31 buttons). To change the base date, the

two arrows can be used. They increase or decrease the actual date

respectively by 1, 7, or 31 days according to the selected time period.

The trends of the selected variables are now displayed in the graph area.

PowerSoft


5.3.3 PREDEFINED TRENDS

To simplify the use of this module, a series of predefined trends are

available using the box in the top left square. For each instrument,

selectable in the upper box, a number of predefined combinations of

variables can be selected. The chosen variables of the instrument are

displayed with reference to the current day. It is then possible to modify

one or more variables or instruments, or modify the displayed date or

period.

NOTE: other predefined trends can be added to the system. Please contact

the supplier for the relevant instructions.

5.3.4 OTHER TOOLS

Other tools, such as the zoom, the cursor, the colour customisation, and

the comparison with the tariffs are available.

5.3.5.1 THE ZOOM

The trends can be analysed in detail using the zoom function. To zoom a

graph, click on a point of the graph area and drag the mouse to the bottom

right direction. The rectangle identified in this way represents the part of

the graph that will be enlarged.

PowerSoft


To return back to the original graph, press the unzoom button on the very

right of the tool bar.

To unzoom the graph, it is also possible to drag the mouse to the top left

direction.

5.3.5.2 THE CURSOR

To better display the mouse position in order to analyse and compare the

graph values in the variables boxes, it is possible to use a cursor. Pressing

the relevant button, in the right of the tool bar, a vertical line is associated

to the mouse standard cursor. To disable the cursor, press the button again.

5.3.5.3 DISPLAYING OF THE TARIFFS

This function is available only if the optional module PWS-Tariff is

available. Clicking the T button on the tool bar it is possible to display, in

the background of the graph area, the different colours associated to the

tariffs. In this way it is possible to correlate in an easy and immediate way,

the trend of the consumptions and their costs.

The contractual powers, in function of the tariffs, can be displayed in the

graph together with the demanded power, in order to evaluate any

exceeding or any critical situation.

5.3.5.4 COLOUR CUSTOMISATION

The colours of the four different trends are customisable by the user using

the relevant buttons (the vertical rectangles which indicate the trend colour

in the legend boxes). Clicking on them, the Colours dialogue box appears.

Once a new colour is chosen, the system automatically changes the trend

colour.

PowerSoft


5.3.5 EXPORTING THE TRENDS

Every graph can be exported as a file or printed. The relevant buttons are

available in the bottom left area.

The graphs can be exported:

in wmf format (windows media format), that is a vectorial

format

in 24-bit bmp format

5.4 SETPOINT CONFIGURATION (PWS-ALARM MODULE)

This module allows the configuration, for each instrument connected and

for each one of the relevant variables, of an upper and/or lower setpoint/s.

PowerSoft


To configure a setpoint, an instrument is to be selected first. The list of all

the connected instruments is available on the left. All the variables of the

selected instrument are listed in the central box. Two indicators are shown

close to each variable. The SW indicator shows if any software alarm

connected to that variable is enabled (green), disabled but configured (red),

or disabled and not configured (grey). The HW indicator shows if any

hardware alarm connected to that variable is enabled (green), or disabled

(red). If HW is enabled and in case of alarm, the digital output of the

relevant instrument (the first one, or the first one of slot D, in case of

modular instrument) is activated. This output is to be set as “REM”

directly on the instrument.

When the variable to be controlled is selected, in the box on the right, the

details are shown. In this box it is possible to: choose the setpoint to be

activated (upper and/or lower); edit the activation and deactivation

setpoint; enable or not the hardware alarming.

The activation setpoint cannot be equal to the deactivation one, but they

are to differ at least by 2% of the activation one. In case of wrong selection,

the system automatically helps the user to set the right values.If the same

setpoint on the same variables are to be set in different instruments, a

copy/paste function is available. When the setting is done in one

instrument, its name is to be right clicked choosing copy. After selecting

the other instruments, right click on them to perform the paste function.

PowerSoft


5.4.1 SETPOINT ON THE CONTRACTUAL POWER

This function is available only if the optional module PWS-Tariff is

available.

On the bottom of the window, it is possible to configure an alarm based on

the contractual powers (depending on the current tariff). The contractual

powers are to be set in the Tariff Management module (PWS-Tariff).

The box, different according to the instrument, allows configuring a

setpoint on the instantaneous system active power measured by the

instrument

The alarm can be software only or software and hardware as per the other

alarms.

The setpoint is to be set as a percentage of the actual contractual power

(the percentage is fixed for all the tariffs). The setpoint is therefore

dependent on the actual tariff.

After configuring and confirming the parameters, the system controls the

instantaneous system active power comparing its value with the described

setpoint.

Example: the system active power value acquired at 11.00 from the

instrument named 01_TCP1 is 185kW. The system checks if the Enable

contractual setpoint alarm (SW) box is enabled: in this case the contractual

power of the tariff relevant to hour 11.00 is acquired (for example it is 200

kW). The setpoint is 90% of 200kW that is 180kW. The instantaneous

PowerSoft


value is compared with the setpoint: since 185kW is higher than 180kW,

there is an alarm condition. The alarm is highlighted in the synoptic, in the

real-time pages and in the active alarm window that automatically pops up.

Only if the Enable contractual setpoint output (HW) box is enabled, a command

is sent to the relevant instrument in order to switch on its digital output.

When the actual tariff varies, the setpoint changes proportionally. If for

example the new contractual power is 220kW, the new setpoint is 198 kW.

5.5 TARIFF CONFIGURATION (PWS-TARIFF MODULE)

This module allows configuring the tariffs and the relevant contractual

powers in a dual- or multi-tariff system. It is possible to easily implement

the multi-tariff schedule that is emitted by each Country Energy Authority.

The window of this module is composed of 3 parts:

- a calendar of the whole year (table A);

B

C

A

PowerSoft


- a table including the tariff associated to each hour of the day

(table B);

- a table where a different contractual power and identification

colour can be associated to each tariff (table C).

5.5.1 THE TARIFF INFORMATION

The calendar shows all the days of the year, to each of which a certain

colour is associated. Each colour represents a different subdivision of the

day in time bands characterised by a defined tariff according to the

Country’s energy regulations. If the day number is in bold characters, it

means that it is a festive day (this indication does not have any effect: it is

only a memo). To add or modify any festive day, the Holiday section of the

bandscolor.cfg file (on the PowerSoft/Configurations folder) is to be

manually modified. The displayed year is shown on the top of table A. The

arrows allow browsing the previous or following years.

Clicking a day of the year in the calendar (table A), the relevant subdivision

in time bands is displayed in table B. In table B, the tariff number and

colour are associated to each hour of the day. Note that the colours of the

tariffs are independent of the colours of the days.

In table C it is possible, by associating a colour, to enable the tariffs (up to

12) and to assign a maximum contractual power to each tariff (to be used in

the graphical trends module and in the contractual alarm management).

5.5.2 MODIFICATION OF THE TARIFFS

5.5.5.1 TARIFF COLOURS AND RELEVANT CONTRACTUAL POWER

To modify the colour associated to a tariff, double click on the colour box,

on table C. The colour dialogue box appears. In the next box, the

contractual power of that tariff can be edited.

PowerSoft


5.5.5.2 SETTING OF THE DAY COLOURS

Each day of the calendar (table A) has a particular colour, that is the same

of each day with the same time bands subdivision. Double clicking on a

day, the colour dialogue box appears. Changing the colour of a particular

day, all the days with the same time bands subdivision assume the same

colour.

5.5.5.3 SETTING THE TIME BANDS

To set the time bands in a day, the number of the actual tariff is to be

edited in the proper cells relevant to the hours composing that time band.

All the cells with the same tariff assume the same colour; the new

configuration of the day is valid, only after confirmation, by pressing the

Set button. To assign the same configuration to other days, it is not

requested to repeat the same procedure more times: a copy/paste function

is available. The day is to be selected in the calendar (table A) and the Ctrl-

C keys are to be pressed (or right click choosing Copy). To paste the

configuration to another day, select the latter and press Ctrl-V (or right

click choosing Paste). To paste the configuration on more days, the paste

command is valid even in case of multiple-day selection.

5.5.5.4 SAVING THE TARIFF CONFIGURATION

To save a new configuration or the modifications, press the Save button on

the bottom. Pressing Cancel all the modifications are cancelled and the old

configuration is displayed. For this reason it is advisable to save frequently

when introducing any modification.

When modifying the setting, if trying to change the displayed year, the

system warns the user that the last modification has not been saved and

asks if it is to be saved (Yes button) or not (No button). The Cancel button

allows cancelling the attempt to change the displayed year.

PowerSoft


5.6 COSTS ESTIMATION (PWS-BILL MODULE)

This module allows estimating the costs due to the energy, water and gas

consumptions measured by a defined instrument, or by a group of

instruments in a selected period.

It allows analysing the daily trend of the costs in the selected period too.

5.6.1 COSTS CALCULATION

The costs calculation can be carried out:

- for a single instrument, using the “Report” tool: the costs

relevant to each item of the supply contract are listed in the

report.

- for a group of instruments, using the “Global report” tool: the

total costs and the total consumptions (kWh, kvarh or m3) of

each instrument of the selected group are listed in the report.

5.6.2 REPORT OF A SINGLE INSTRUMENT

The “Report” tool provides information regarding the total costs and all

other items of the supply contract relevant to a single instrument.

The procedure to get the report is the following:

1. Select the instrument by means of the relevant drop-down menu.

2. Select, by means of the relevant drop-down menu, the contract to be

considered. The energy, gas, and water contracts are listed together but

are coloured differently (blue for water, red for gas, green for electrical

supply).

PowerSoft


3. Select the reference period. The period choice is free since it is

possible to select both starting date/hour and ending date/hour.

Clicking on the date box, a calendar appears while, to select the hour,

hours, minutes, and seconds can be highlighted by using the mouse

and the relevant value can be modified by means of the arrows on the

right side of the same box.

4. Press the Calculate button.

In the central area, if the Report section is selected, the summary of the

consumption costs appears.

The report can be printed or exported in html format, using the buttons on

the bottom left.

PowerSoft


5.6.3 REPORT OF A GROUP OF INSTRUMENTS (GLOBAL REPORT)

The “Global report” tool provides information regarding the total costs

and total consumptions relevant to one or more groups of instruments.

The procedure to get the global report is the following:


considered. The energy, gas, and water contracts are listed together

but are coloured differently (blue for water, red for gas, green for

electrical supply).

2. Select the reference period. The period choice is free since it is

possible to select both starting date/hour and ending date/hour.

Clicking on the date box, a calendar appears while, to select the hour,

hours, minutes, and seconds can be highlighted by using the mouse

and the relevant value can be modified by means of the arrows on the

right side of the same box.

PowerSoft


3. On the left of the screen, a diagram includes the list of all the

configured instruments, grouped COM line by COM line. Each

instrument can be included in the group to be analysed by means of

the tick box on the left of its name. The global report considers all the

selected instruments.


In the middle of the window, in an area named “Report”, a table summarises

the costs and the total consumptions (kWh, kvarh or m3) relevant to the

selected contract and to the selected instruments. This operation could take

several minutes, according to the number of selected instruments and to

the length of the selected period. During the calculation a progress bar,

below the “calculate” button, shows the status of the operation.

According to the type of the chosen contract, the global report is different

and includes the following information, in addition to the total cost:

- Energy: it shows the total consumptions of active and reactive energy,

the exported energies (if available), and the active power by tariff (if

available and if the PWS-tariff module is active) and the last readings of the

relevant energy meters (actual displayed values).

- Water: it shows the total water consumption (expressed as m3) and

the last reading of the relevant counter.

- Gas: it shows the total gas consumption (expressed as m3) and the last

reading of the last counter.

The global report can be printed or exported in xls format. It is possible to

copy any group of cells directly from the PowerSoft report and paste them

in an existing spreadsheet. The heading row is automatically copied, even if

not selected.

PowerSoft


5.6.4 LOADING AND SAVING INSTRUMENT GROUPS

The “Save group” and “Delete group” buttons helps the generation of

different global report process (different instrument groups and/or

different contracts); the function “Load group” can be called by double-

clicking on the name of an existing group: the user can save, delete, or load

any group to be automatically associated to a selected contract.

Example: some instruments are dedicated to the energy metering, others to

the water metering. Some energy meters can be included in a specific

group associated to an energy supply contract (the group could be named

“Energy meters with ACME Energy Company”, for example). Other

energy meters can be included in another group associated to another

energy supply contract (the group could be named “Energy meters with

National Energy Company”, for example). All the water meters can be

included in a specific group associated to a water supply contract (the

group could be named “Water meters with Niagara Water Company”, for

example). Whenever the user wants, one of these configurations can be

simply loaded (without asking for the selection of the meters and of the

contract any more), a period chosen and the global report be asked for.

5.6.5 GLOBAL REPORT OF ALL THE EXISTING GROUPS

To completely automate the report generation process, the “Export all user

groups” button allows the following event sequence:

- a destination folder, in which all the generated reports are to be

stored, is required;

- for each existing group of instruments:

the relevant global report is generated (indifferently if

relevant to energy, gas, or water)

PowerSoft


the global report is saved in xls format in the previously

defined folder, with a default name composed by the

group name, followed by the contract name and by the

relevant period.

5.6.6 GRAFH OF THE DAILY COST

The “Graph” tool generates the daily cost trend due to the selected

contract and relevant to a single instrument.

The procedure to get the graph is the following:

1. Select the instrument by means of the relevant drop-down menu.


considered. The energy, gas, and water contracts are listed together but are

coloured differently (blue for water, red for gas, green for electrical supply).

3. Select the reference period. The period choice is free since it is possible to

select both starting date/hour and ending date/hour. Clicking on the date

box, a calendar appears while, to select the hour, hours, minutes, and

seconds can be highlighted by using the mouse and the relevant value can

be modified by means of the arrows on the right side of the same box.


In the central area, if the Graph section is selected, the daily graph of the

consumption costs appears.

PowerSoft


The graph can be printed or exported in wmf or bmp format by means of the proper button on the bottom left.

5.6.7 CONFIGURATION

The Configuration section is to be used to set the parameters which

characterise the contract with the supplier. In this section any modification

can be stored by means of the Save button. The Cancel button restores the

last parameters.

The parameters can be different according to the supplier. The default

parameters of PowerSoft meet most of the contracts: taxes, fixed costs of

the installed power, and energy costs (depending on the tariff) are listed.

PowerSoft


If some parameters are different or missing, a customised contract can be

implemented. Please contact the supplier for the relevant instructions.

5.6.8 AUTOMATIC REPORT GENERATION

Any report (relevant to a single instrument, to a group or to all the groups)

can be automatically generated on regular basis using a specific function of

the e-mail module (PWS-mail). The reports are saved in a selectable folder

in the PC where PowerSoft is running and can be e-mailed to one or more

addresses. Further information is available on paragraph 5.10.3.

5.7 ALARMS AND EVENTS

This module allows accessing the historical archive of the alarms (stored

when disappeared and acknowledged) and of all the events relevant to the

PowerSoft


system. The displaying concept is similar to the one described for the active

alarms: in addition there are the system events (such as software start/shut

down, login, output status commands, etc.), written in light blue. It is not

possible to acknowledge any event in this module.

The list can be filtered, acting on the type, subtype, agent, and/or description

field. By the proper buttons in the right top, the filtered queue can be

printed or exported (in xls or csv format).

PowerSoft


5.8 ANALYSIS SUPPORT (PWS-ANALYSIS MODULE)

This module allows carrying out the analysis of the consumptions data

stored in the database, in order to get important information for the energy

management of the company. The module is intuitive and user-friendly like

the other ones but, because of the complexity and of the delicacy of this

kind of analysis, it is recommended that the module is used by expert users

only, to grant the precision and the reliability of the results returned by the

module.

5.8.1 TARGET

The module extracts information from the consumption trends, elaborates

the load profile of each instrument, and suggests the optimal contractual power. To

PowerSoft


do it, a series of options and statistical tools can be exploited. They help the user in

performing the right analysis.

5.8.2 GRAPHICAL STRUCTURE

In the top of the window the instrument and the period to be analysed can

be chosen. The button Load data allows uploading the relevant data from

the database to the software memory.

On the central area, the graph takes up the right side, while on the left there

are the commands and the options necessary for a reliable analysis. Two

sections are available: the Load profile section and the Optimisation one, where

the ideal contractual powers are suggested.

In the bottom, the buttons allow printing or exporting the analysis result

either in wmf (or bmp) format (if the Graph section is selected in the central

area) or in xls spreadsheet (if the Graph section is selected in the central

area).

5.8.3 OPERATIONS

The operations to be performed are suggested in the following paragraphs.

The first step is to generate the load profile graph of the selected

instrument.

5.8.5.1 LOAD PROFILE EXTRAPOLATION

The instrument and the period to be analysed are to be chosen in the top

area, pressing Load data. The Load profile section is to be selected. The load

profiles of that instrument in that period are shown day by day or week by

week according to the daily integration/weekly integration of the Display box.

The weekly integration is suggested to show the long-term consumptions

trend. The daily integration is suitable to analyse shorter periods (a few

weeks).

PowerSoft


To analyse the trend of each day of the week separately (every Monday for

example), the daily integration view can be spitted with separate the days of the

week. Each day, or group of days, can be displayed selecting the proper

boxes in the excluded days list. In this way it is possible, for example, to

understand the differences in terms of consumptions within the week or if

an increase of the consumptions is a general trend or if it happens only in

particular days of the week.

In the database some anomalous data could be present. They can be due to

temporary problems of the instrumentation, of the network, of the

monitored system or plant: those measurements are real but they can affect

the statistical analysis. It is possible to filter these anomalies to get a more

homogeneous set of data.

The available filter is a “median filter” with selectable steps of 3, 5, or 7

data. It means that every 3-, 5-, or 7-data sequence of the original trend, the

value of the central datum will be replaced by the median of the same

sequence. This filter cuts the isolated peaks but preserves the trends

PowerSoft


(increasing, stable, or decreasing): the higher the step, the more

homogeneous the final trend. The aim of this filter is only to clarify and

highlight the trend of the consumptions. It is to be used only for this

purpose and not to carry-out further analysis or calculations.

5.8.5.2 CONTRACTUAL POWER OPTIMISATION

The graph displayed in the section Optimisation shows the consumptions of

the selected instrument in the selected period in function of the time of the

day. Studying the consumptions hour by hour, it is possible to identify the

average consumptions and the maximum values that can be expected by

that instrument. The procedure to get this information is automatic, but it

requires important user’s interventions in order to carry out a correct

analysis.

PowerSoft


After uploading the data, the statistical parameters are to be properly set.

The Resolution indicates the duration of the time intervals in which the day is

split (from 5 to 60 minutes). The Confidence level indicates the probability that

the consumptions of the instrument are below the proposed contractual

power.

Determining the optimal power profile, it is important to understand that

this analysis is meaningless if the consumptions are not constant in the

selected period. In fact, it is useless to find a “typical” trend if it is known

that the consumptions are changing. The procedure described in the

previous paragraph can help in understanding if this analysis can be done,

avoiding any incorrect estimation.

One (or more) day(s) of the week can substantially differ from the other

days; in this case the analysis is to be repeated for each group of

“homogeneous” days. It is possible to tick/untick the days in the Excluded

day section and carry out the analysis; then the operation is to be repeated

for the other days. Consider that a trend which is regularly higher or lower

than the “standard” trend allows to an over-estimated proposed contractual

power.

Even if the previous factors are considered, other anomalous data can still

be present. They can be due to different reasons: holidays during the

working days of the selected period; production stops; strikes; damages or

anomalies in the energy supply.

The holidays can be excluded from the calculation selecting the relevant

days in the Holiday section. In the Excluded days box the desired days can be

added to the holiday list. To remove a wrong day, select it and press the

Delete button.

To delete the other anomalous points (due to occasional and short

damages, production stops, etc.), an automatic filter is available. Press the

2 - erase anomalous points button to execute the filtering. A report (erased

points/total points) is available in the bottom status bar.

PowerSoft


Now the system is able to provide the optimised contractual powers. The

graph displays the arithmetical mean, the median and the variance (that is

the square of the standard deviation) of the demanded power.

The arithmetical mean of the power is not a reliable value to estimate the

typical consumptions, because any anomalous point can lead to an

inaccurate estimation.

The median estimates the typical consumptions with a higher accuracy; this

parameter allows achieving accurate estimation even if anomalous points

are still present, but the number of the analysed samples is to be high

enough.

Variance and standard deviation estimate how the values are distributed

around their mean or median. The higher the variance, the wider the

distribution of the values around the mean/median.

These parameters are very important in determining the optimal

contractual power: the suggested powers are in fact defined as the median

plus the standard deviation (or 2 or 3 times the standard deviation). If the

analysis has been correctly performed (as suggested before) and without

any unpredictable events, setting the Confidence level as Low, the probability

that the actual requested power is lower than the suggested one is 68.3%; if

it is set as Middle the probability is 95.4%, while if it is High the probability

is 99.7%.

PowerSoft


The suggested contractual power can be defined, choosing Match max on

the Confidence level selection, as the sequence of the maximum of the values

relevant to each one.

The definition for the optimal contractual power is to be chosen by the

user considering the fixed cost of the power (cost per kW), the number of

expected overpower demands, and the cost of the penalties due for them.

On the graph of the optimised power, the following data are displayed: the

blue dots are the power values stored in the database (and relevant to the

selected instrument in the selected period); the light green line is the median

of the power (blue dot) values; the dark green one is relevant to the

arithmetical mean of the same data. The red line is the suggested

contractual power.

The first visual analysis is to detect any anomalous points: their presence

can be deduced in case of scattered blue points and if the median is far

from the arithmetical mean. The result is that the proposed red line is

meaningless with respect to the actual consumptions (the ideal situation is

when the red line is close to the higher of the blue dots). The anomalous

points are to be deleted (as explained above) excluding the

holidays/failure/strike days and with the automatic filter (2- Erase anomalous

PowerSoft


points button). When the analysis is consistent with the expected results, the

graph or the correspondent table (Grid tab) can be used, printed, or

exported.

5.8.5.3 IMPORTANT NOTE

This analysis process has been developed to be automatic, stable, and

accurate, even in case of anomalies stored in the database. As all the

automatic processes, in case of unexpected or heavy anomalies, it can fail.

The critical ability and supervision of the operator is thus indispensable to

avoid any incorrect analysis. For this reason this module has been called

Analysis support, being actually a useful tool for the final analysis which is to

be carried out by the user.

PowerSoft


5.9 THE WEB-SERVER (PWS-WEB MODULE)

This module allows remotely accessing the real-time data, the database, and

the reports using a standard browser.

Launching the module from PowerSoft allows accessing the following

window.

From this window it is possible to activate or deactivate the web server

function by means of the relevant buttons. The log of the events relevant

to the web server allows the user to be updated on the module status. Only

the most important messages are shown, unless the Show all messages box is

ticked. To clear the log, the relevant button is to be used.

The web server module has been optimised to be used with web clients as

Internet Explorer version 6 or higher.

PowerSoft


The functions available via web are similar to the ones available for a guest

user of PowerSoft (plus the simplified Analysis support): for their

description, please see the relevant paragraphs.

To remotely access the PowerSoft web server, the IP address of the PC

where PowerSoft is running is to be edited in the address bar of Explorer.

It is requested to log in before accessing the information: only one access

level is available and it is common both to the Users and to the

Administrators.

The web server opens a pop-up window to warn about a new alarm

situation, as PowerSoft does. Note that this function could be considered

an undesired function and then excluded. The web client is to be set not to

filter the pop up windows to exploit this function.

If the pop up windows are not desired, it is still possible to manually open

the active alarm list.

5.9.1 THE TOOLBAR AND THE MODULES

One of the main differences between consulting PowerSoft directly or

remotely is the toolbar.

The toolbar allows activating all the functions of the installed modules.

Clicking any available entry on the toolbar, a new Explorer window, where

the parameters necessary to the execution of the required report are to be

entered, is opened.

To get a graphical trend, for example, click on Trends on the toolbar and fill

the parameter boxes in the following form.

PowerSoft


The required parameters are the same as the local version of PowerSoft,

but are listed with a different layout. After setting the parameters, pressing

on the Execute button the desired report appears.

The picture can be exported right clicking on it and choosing Save image as...

5.10 AUTOMATIC E-MAILING (PWS-MAIL MODULE)

This module allows the automatic sending of E-mails on regular basis or as

a consequence of selectable events. Its configuration is composed of two

parts, available only to the Administrators:

The configuration of the E-mail parameters

The configuration of the events and of the data to be sent

5.10.1 E-MAIL PARAMETERS

The module windows are composed of two sections: the first one displays

the log of the events connected to the e-mailing; the second one includes

the form to configure the automatic e-mailing.

To send an E-mail the following parameters are required:

The SMTP server (the server for the outgoing mail)

The server “user ID” (if required)

The server “password” (if required)

An existing e-mail address

PowerSoft


These parameters are the same used in the e-mail clients (Outlook, Eudora,

Thunderbird, etc.) and can be copied from their configuration parameters.

To check if the parameters are correctly set, a test e-mail can be sent.

5.10.2 E-MAIL SCHEDULER

The E-mail module enables the Scheduler menu:

The configuration relevant to the e-mailing is possible selecting this menu.

PowerSoft


It allows programming to whom the mails are to be addressed, when and

with which attachments.

A new scheduled e-mail task can be added pressing the Add new button,

while a task can be deleted, after confirmation, with the Erase selected button.

Adding a new task, the first choice is when the mail is to be sent:

- On regular basis. The mail can be sent once a day (selecting the

desired hour), once a week, or once a month (selecting the

day and hour).

- On event: it is possible to send a mail when a

communication error or a setpoint alarm appears. These

events can be filtered applying the rule to all, some or only

one instr
